Pipe clamp



PIPE' CLAMP J. GURSCHKE Filed Jan. '7, 1931 WITNESS:

Patented oet. 13, 1931 UNITED STATES-"PATENT OFFICE- JOSEPH GURscHKE, or SANFBANcIsco, CALIFORNIA PIPE CLAMP Application mea January 7, 1931. serial No. 507,252. f

My present invention has reference to a clamp for holding pipe sections so that the pipe line will hang straight or plumb in a well or likewise for holding the sections of a 6 pipe line when the same are coupled together.

The object of the invention is the provision of a clamp for this purpose characterized by simplicity in construction and reliability and efficiency in practical use.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawings:

Figure l is a top plan view of the improvement in operative position.

yFigure 2 is a side elevation thereof.

Figure 3 is a view looking toward the jaw end of one of the clamps, the pivotal connecting bars for the clamps being in section.

Figure l is a side elevation with parts in section to more clearly illustrate the gripping engagement between the jaws of the clamp and the pipe, the latter being also in section.

Figure 5 is a plan view of one of the connecting bars for the clamp.

, As disclosed by the drawings two similarly constructed clamps are employed. Each of the clamps is of substantially rectangular formation but has a widened portion extending from its jaw end to approximately the center thereof. lThe clamps are each indicated by the numeral l and the jaw ends thereof are arranged angularly and their confronting faces concaved and formed with 35 gripping teeth 2. The mentioned widened portions of the clamps, that is, the portions thereof provided with the jaws are also widened with respect to the rear and outer ends of the clamp bodies, as clearly disclosed Vby the drawings and the reduced outer ends of the clamp bodies have their lower corners provided with projections 3 that are designed to rest upon suitable supports 4 opposite a well 5. The widened and thickened confronting ends of the clamps have their upper edges formed with outwardly extending flanges 6 which overlie rounded depressions 7, and in these depresisons there are received the offset and rounded ends 8 of the connecting bars 9 for the cooperating pairs of clamps. Pivots 10 passthrough the ends 8 of the connecting bars 9. Y

By reference to the drawings it will be noted that the rounded portions 8 of the bars 9 received in the depressions or pockets 'i 55 permit of the frictional contact of the inner faces of the said bars with the outer faces of the clamps so that the clamps are held by the bars in proper alinement. When the clamps are swung to horizontal position the flanges 6 60 will contact with the upper edges of the bars 9 which will prevent further swinging of the clamps in what may be termed a downward direction. The clamps are arranged anguf-v, larly with respect to each other, as disclosed i by Figures l, 2 and 4 of the drawings when a pipe 11 is gripped therebetween. The pipe 11 cannot descend into the well 5 when engaged lby the clamps, but pipe sections can be held in vertical position to permit of the coupling thereof to produce a pipe line when one of the pipes is supported by the clamps. The clamps must be swung away from each other to permit of the descent of the pipe line into the well but the pipe line can be readily drawn from the well as the upward movement thereof will cause the aws of the clamps to move away from each other by the frictional engagement of the pipe l1 therewith, and also because of this frictional engagement the pipe cannot be lost or accidentally drop into the well.

The improvement is of a simple nature and the advantages of the construction will, it ism thought, be understood and appreciated S5 without further detailed description.

Having described the invention, I claim:

1. A pipe clamp comprising two clamp members having their confronting ends concaved and arranged at opposite angles and formed with gripping teeth, said clamps from their jaw ends having their upper edges flanged outwardly and having their sides formed with annular depressions which theflanges overlie, connecting bars for the pair J0 of clamps, each having widened ends rounded in the same direction and received in the depressions and pivoted to the clamps and the outer edges of the said bars being in the path m0 of engagement with the flanges of the clamps.

2. A pipe clampv ycomprising two clamp members having their confronting endsrconcaved'and'arranged at opposite angles and l Y formed with gripping teeth, said clamps from their j aw ends having their upper edges flanged outwardly vand having their sides Y formed with annular depressions which the. flanges overlie,' connecting bars for the-'pair of clamps, each having widened ends rounded Y 'in the same direction and received inthe depressions and pivoted to' the clamps and-.the outer edges of the said bars being in the path of engagement with the flanges of the clamps, Y 'the outer ends of thelamps beingredueed in,l I width and having proj eotionsextending from their lower corners. z l l In testimony whereof I affix my signature.
